I have some concerns with Brandon Jacobs' durability, but he's still one of the top free agents available this spring. Jacobs has proven that he's nearly impossible to tackle, and his ability to wear down defenses is something the Giants can't afford to give away.

Darren Sproles, Chargers. Age: 26. Franchised by Chargers

Darren Sproles will never be an every-down back in this league, but he's such a great weapon to have on offense and special teams. He's a threat to go the distance at any time, as the Broncos found out on Week 17.

Derrick Ward averaged 5.6 yards per carry this season and also caught 41 passes. However, his age makes him a risky multi-year signing for anyone. Also, Ward didn't carry the ball more than 20 times in any game in 2008.

Fred Jackson (ERFA), Bills. Age: 28. Tendered by Bills

One of the best change-of-pace backs in the NFL, Fred Jackson will definitely be retained by the Bills for a minimal tender. It's worth noting that Jackson rushed for 136 yards on 27 carries against the Patriots in Week 17.

Cedric Benson was brilliant for the Bengals down the stretch. He totaled at least 130 yards in each of his last three games. Benson would be rated higher, but the over-under on his DUI arrests this spring stands at 9.5. Vegas is taking bets now.

Larry Johnson, Chiefs. Age: 29. Signed with Bengals

Larry Johnson could be a great short-yardage back for a team like the Texans. However, he's far from an every-down runner at this point.

An interesting free agent. Is Edgerrin James done, or was his lacking production in Arizona the result of poor blocking? We'll soon find out. James hasn't averaged more than 3.9 yards per carry since leaving the Colts after the 2005 season.

Tatum Bell, Broncos. Age: 28.
If you can keep him away from cash registers and luggage, Tatum Bell can be pretty effective. Bell totaled 117 yards and two touchdowns against the Chargers in Week 17.

Warrick Dunn, Buccaneers. Age: 34.
Warrick Dunn just turned 34, but he totaled 1,116 yards in 2008. He's a solid third-down back who will find a new home.

Fred Taylor, Jaguars. Age: 33. Signed with Patriots

I can't believe the Fred Taylor era is over in Jacksonville. Taylor, 33, averaged 3.9 YPC last year despite playing behind the most banged-up offensive line in the NFL. Taylor can still be an effective reserve running back for a year or two.

Correll Buckhalter, Eagles. Age: 30. Signed with Broncos

Correll Buckhalter has an extensive injury history and can't be a starter in the NFL. He's a solid backup.

LaMont Jordan maintained a 4.5 YPC average in 2008, but at this point in his career, he's nothing more than a backup/committee back.

Dominic Rhodes, Bills. Age: 30.
The last year Dominic Rhodes averaged more than four yards per carry was 2004. He maintained a figure of 3.5 this season. He's an adequate backup, but he's clearly over the hill.
